@PianolasonMars I have several new notes on your work, but we'll get the broad stuff out of the way first: I like that your story has taken on a more singular focus. The beginning contained a lot of setups and world-building, but there was a certain lack of 'where is this going'. Halfway through the script, we've got intrigue, betrayal, personal honor, team loyalty, and all the rest of the juicy stuff your story is really about. In draft 2, your first task is probably going to be to introduce some of these story elements earlier....but let's keep writing draft 1 for now.
I took notes throughout my read, so we'll go through one by one:
(1) The word 'survivalist' is a whopping four syllables, so it's an awkward size for the dialog sometimes. I really like the name "Locust", and I wish the home team had a name that's more fun to say. It's a nibbly little comment, but titles are more important than you sometimes realize.
(2) When you write that 'locusts are crawling' in the storage space, the statement is a little confusing. I'm not sure how you can easily differentiate between the human locusts who have guns and want to kill you and the little green locusts that chirp in the summer.
(3) Transitions! This is just a screenwriting carpentry note - you don't have a lot of "CUT TO" or "DISSOLVE TO" notations between one scene and the next. Add in those transitions - they're basically expected.
(4) When the Shaman is talking, the speech ends with "I want you to understand something: You're not going to be healing the body. What we do has nothing to do with the flesh." I think you should end the line there - that says more than any further explanation could offer.
(5) You're using the word "sow" when you mean "sew". Easy mistake to make, easy mistake to fix.
(6) Tell us the disposition of the battle when Doc wakes up. He's knocked out in the middle of a fight, we don't know what happens, and then we're left to infer that the good guys won. You don't have to devote too much time to it, but a couple of lines saying "What happened?" "Oh, we won" would patch that leak.
(7) I don't think they should call their attack operation an 'extermination crew' - even if that's the end goal of the attack. People have a way with euphemisms when they're hell bent on doing something horrible. Something like a 'defense squad' or a 'diplomatic mission' would be a nice little spike of irony.
You're over 50 pages! That's half a screen play or an entire TV pilot!!! What else is there to say? The facts speak for themselves. Keep that writing up.
